  •  HOW / Vascular Access Potency


How to maintain arteriovenous fistulas primary potency rate?


Management of Vascular Access

Use hand grasp exercises, 500 times a day to prevent fistula embolism and promote smooth blood circulation 24 hours after the surgery. Remove any restrictive clothing or jewelry from the arm. To prevent injuries, place an armband on the patient or a sign over the bed that says no BP measurements, venipunctures, or injections on the affected side. When blood flow through the vascular access is reduced, it can clot.


Position the patient's arm so the vascular access is easily visualized. Palpate the vascular access to feel for a thrill or vibration that indicates arterial and venous blood flow and patency. Auscultate the vascular access with a stethoscope to detect a bruit or "swishing" sound that indicates patency. After dialysis, assess the vascular access for any bleeding or hemorrhage. Avoid trauma to or excessive pressure on the affected arm and ensure that dialysis needlestick locations are rotated to prevent stenosis and thrombus formation.
